If there is a common cliché in age-gap romances, it's the young man chasing the woman. Why is this? Because it is often explained that a "mature" woman doesn't want to see the interest of a young man and is the last one to fall in love only after all the efforts of the pretender.
So the cliché is in place and we can now focus on the content of the story. I want to say that there is nothing new on the horizon, childhood friends who lost touch when the woman started her professional life. She has had several relationships, he hasn't because she's the only love of his life. So why say I liked this drama?
Because there is no room for misunderstanding in their relationship, the watchword is communication even if the subject is painful. Lu Zheng An knows what he wants and why he wants it. He isn't childish, he just doesn't want to sacrifice his happiness (his love) for things he considers futile. I like it when he says that he isn't against wealth and fame as long as it doesn't affect his lover.
Lin Yang questions her decisions and behaviour towards her boyfriend when she knows that she's acting in his interest and not in their relationship and that sometimes being the oldest doesn't necessarily mean the wisest and most rational. I like the fact that this drama shows us that a woman, even if she is independent and strong, allows herself to lean on a shoulder when she needs it. It is not necessarily her boyfriend, but also her friends and family.
